The biggest ASDA store in Leyton that operates 24/7.Avoid the self check-out if you don't want to spend an hour checking out 5 products and 'seeking assitance', unless of course you're a professional.
Early morning is good shopping but very few cashiers. Drink very cheap own brand tast like the originals. Always offers on to tempt you in.Also have thier own petrol station next to store.
Try the jerk chicken from the hot counter it's awesome. Don't forget to ask for reggaereggae sauce on it, they hide it behind the counter and don't offer unless you ask.
